“Carl Sagan, in addition to being a teacher of science, was a teacher of morals and empathy. He advocated for free speech, compassion, education, civil liberty, racial equality, gender equality, skepticism, and creativity. His views are continuing to inspire generations. Some, like me, have followed in his footsteps and seek to explore the wonders of science while improving the human condition. Carl had a hopeful view for humanity and he devoted his life to make that view a reality. Carl Sagan was certainly one of the best of us and he should be remembered for his great accomplishments.”

As for Rosetta … I still can’t believe they pulled that off. Chasing a comet for ten years and then putting a lander on its surface. What audacity to even imagine such a thing, much less try it — and succeed!

Poor little Philae. A bad bounce into a shady spot and its historical mission ends. I hope it can gather enough sunlight for a future power-up, but I’m not optimistic. Meantime, WOW. What an accomplishment!
